GS4B036802FT

GS4B036802FT Description

The GS4B036802FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 68KΩ resistance value and a tight ±1% tolerance, this ceramic-based network ensures reliable signal integrity in demanding environments. Its ±25ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for circuits operating at 70°C to 125°C, with a maximum voltage rating of 100V. The SOIC-C series construction offers robust mechanical stability, featuring gull-wing termination for secure surface mounting.

GS4B036802FT Features

• Ceramic substrate for enhanced thermal and mechanical durability.
• Thin-film technology ensures low noise and high precision (±1% tolerance).
• Bussed (BUS) configuration simplifies circuit design for common-node applications.
• Compact dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• Wide operating range: -55°C to +125°C (derated power up to 125°C).
• RoHS non-compliant (note for legacy or exempted applications).
• Tube packaging for automated assembly compatibility.

GS4B036802FT Applications

Ideal for precision analog circuits, voltage dividers, and bus termination in:

• Industrial control systems requiring stable resistance under thermal stress.
• Telecommunication hardware (e.g., signal conditioning modules).
• Medical devices where consistent performance is critical.
• Automotive test/validation setups (though not PPAP/automotive-qualified).
• Power management PCBs leveraging its 100V rating and low TCR.

Conclusion of GS4B036802FT

The GS4B036802FT stands out for its ceramic thin-film construction, bussed topology, and exceptional thermal stability, making it a superior choice over polymer-based networks in high-reliability designs. While not RoHS-compliant, its precision (±1%, ±25ppm/°C) and compact SOIC footprint cater to legacy and exempted industrial applications. Engineers will value its balance of performance, durability, and ease of integration in space-constrained, thermally challenging environments.
